Herein we propose a new mechanical model for interpretation of volume‐pressure relationships of the bladder in both the collection and in the evacuation phase. Contractile tissue is ascribed plastic properties. The static volume‐pressure relation is related to a plasto/contractile‐elastic tissue component. In contrast to other models, the elastic element in series with the contractile element corresponds to tissue elasticity, which also determines the static volume–pressure relation. Viscoelasticity is more relevant in the evacuation phase than in the collection phase.
